The free future race is good for AFTERNOON HEATS at any Canadian Sprint, Super, or Beast. If you volunteer at a Sprint, you can use your free race at a Super or a Beast, and vice versa. The Free Future Race registration works as any other registration. You can sign up with a team and choose the time block you want to race in (you can pay an upgrade fee to the Elite, Competitive, or Morning Heats).
The free race from volunteering at a Sprint, Super or Beast is not valid for specialty events including but not limited to Junior Races, Charity Races, Ultra Beasts, or Agoges.
